Antione Kaliph Cauley, 27, walked into the Laurel police headquarters alone about 12:30 p.m. Sunday. He was wanted on charges of first-degree vehicular homicide in the death of Matthew Cavin, 23, Friday night. A lawyer for Cauley could not be reached for comment Sunday.

Witnesses told police an argument between the two men spilled out into a town house parking lot on South Arbory Lane in Laurel. Cauley was seen striking Cavin with the front of his SUV and then fleeing the scene with a female passenger.

Cavin's body was recovered from beneath a second vehicle and he was pronounced dead at the scene, police said.

Prosecutors announced new indictments Monday of Baltimore jail staff, the same day a top corrections official testified in the federal corruption trial of eight inmates and corrections officers about the difficulty containing misconduct in the system.
